I played every skill position in high school except qb. I new the oline blocking scheme because I played TE, FB, and RB, but also new the qb reads because I was a receiver. I never understood defense though. They tried to get me to play some safety too, but I was lost out there.
I say this because your post just confused the hell out of me. Their were times last year when Tomme Mark was the end man on LOS in a 4i. I always wondered why teams didn’t run outside zone every time and just hook him. But after reading your posts and an article posted on another thread about the 3-3-5, I realized that I have much more to learn. It is way more than simple alignment. Everyone has an assignment, but you trick the offense by not showing your hand before the play. The less down lineman, the more tricks you can do. Unless you have the 2015 stl rams 4-3 dline, where every player is a star, then it is probably a good idea to confuse the offense and make them think rather than firing off the ball. Similar assignments, but you start from different places.
